Modeling of Vertical Shaft Impact Crushers
natural sources, like gravel, or manufactured crushed rock. VSI crushers can be used to create this machine sand but existing mathematical models make it hard to plan new sites and achieve a viable replacement to the natural sand. In this thesis, the use of vertical shaft impact crushers to crush aggregate rock to rounder particles is investigated.

Impact Crusher Working Principle
Impact crushing crushing grinding method. Shear crushing is accomplished by breaking along or across lines of cleavage. It is possible, when required, for a crusher to use a combination of two or three of these principles. The selection or sizing of a crusher is much helped by measuring the rock's hardness during engineering.

Modelling and simulation of particle breakage in impact crushers
The minimum size of the particles that undergo breakage is assumed to be a function of the impact energy and the feed rate. The model predictions are compared with experimental data obtained for limestone treated in a pilot-plant hammer crusher. The dependence of the product size distribution on the rotor velocity is investigated.
